Enyanisweni, sonke siyazi ukuba imveliso yokubonisa i-LED yangaphakathi kungakhathaliseki ukuba umgangatho ulungile kangakanani, kukho ukugcinwa, ixesha lokuphila kwayo ngaphezu komgangatho wemveliso ngokwayo, ukugcinwa kungundoqo obalulekileyo kwi-Indoor LED ukubonisa, njengazo zonke ezinye. iimveliso, kunengqiqo ukuba neengxaki.Into esinokuyenza kukufumanisa ngcono iingxaki ngaphambi kokuba bafike benze umsebenzi wokulungisa kwangaphambili kangangoko kunokwenzeka.Ngoko ke zeziphi iindlela zokugcina kunye nokubonwa kwesikrini sokubonisa i-LED yangaphakathi?Umsebenzisi kufuneka enze njani umsebenzi olungileyo wokubona isikrini se-LED sangaphakathi?
1. Uvavanyo lokumelana nesikrini se-LED yangaphakathi, indlela yovavanyo yokumelana nomboniso we-LED yangaphakathi, kufuneka sithumele i-multimeter ukuchasana, okokuqala ukubhaqwa kwelinye iqhekeza lebhodi yesekethe yesiqhelo ukuya kuxhathiso lomhlaba kwinqanaba elithile, kwaye emva koko sibona uvavanyo olufanayo lwenqaku elinye. yebhodi yesekethe efanayo, ukuba kukho ukungafani nokuchasana okuqhelekileyo kwaye uyazi ukuba kukho ukungafani ngoko ububanzi bengxaki yokubonisa okukhokelela ngaphakathi, okuchaseneyo kuya kuba.
2. indlela yokukhangela umbane wangaphakathi we-LED: ukubonwa kwe-LED yangaphakathi yokubona umbane kukulungelelanisa i-multimeter kwifayile yombane, ukubona isekethe ekrokrelayo kunye nengxaki yenqaku ukuya kumbane ophantsi, xa kuthelekiswa nokwangaphambili kuqhelekile, ukuze ibe nakho. ekulungeleyo ukumisela ingxaki.
3. Umboniso we-LED wangaphakathi ubonisa indlela yokukhangela isiphaluka esifutshane: i-LED yangaphakathi ibonisa indlela yokukhangela isiphaluka esifutshane kukulungelelanisa i-multimeter kwibhloko yokukhangela isiphaluka esifutshane, ukuze ukwazi ukubona ukuba kukho isiganeko esifutshane.Ukuba kukho i-short circuit phenomenon, kufuneka isonjululwe ngokukhawuleza.Isenzeko esifutshane sesekethe yesikrini se-LED sangaphakathi sikwayeyona nto ixhaphakileyo yemodyuli yokubonisa i-LED yangaphakathi.Ukwengeza!Ukufumanisa isiphaluka esifutshane kufuneka kwenziwe xa isiphaluka sivaliwe ukuphepha umonakalo kwi-multimeter.
4. Uvavanyo lokuhla loxinzelelo lwangaphakathi olukhokeleyo: uvavanyo lokwehla loxinzelelo lwangaphakathi olukhokeleyo kukucinezela i-multimeter edluliselwe kwiimvavanyo zokulahla ze-diode, kuba umboniso okhokelwayo wangaphakathi yonke i-IC yenziwe ngamacandelo amaninzi eyunithi, ke xa ikwiphini inikwa amandla xa iya kubakho kwisikhokelo |ukuwisa unyawo.Ngaphantsi kweemeko eziqhelekileyo, ukuhla koxinzelelo kwi-IC pin yomzekelo ofanayo kuyafana.
Kwiindlela ezininzi zangaphakathi ze-L ED zokubonisa iindlela zokugcina sinokuzigcina engqondweni, ngexesha lokubhaqwa, ukuphepha umonakalo womboniso wethu wangaphakathi we-LED, kunokuba kuhle kakhulu ukwandisa ubomi benkonzo yomboniso wethu wangaphakathi we-LED.Ngale ndlela, ayikwazi nje ukwandisa ixesha lokusetyenziswa kwayo, kodwa kunye nokugcina inkcitho yohlahlo lwabiwo-mali olungeyomfuneko.
